Apply the BU-3DFE (Binghamton University 3D Facial Expression) Database 83-point facial semantic labels.

The semantic labels applied are as follows:

  • right_eye

  • left_eye

  • right_eyebrow

  • left_eyebrow

  • right_nose

  • left_nose

  • nostrils

  • outer_mouth

  • inner_mouth

  • jaw

  • x (LabelledPointUndirectedGraph or PointCloud or ndarray) – The input labelled point graph, pointcloud, subclass of those or array to label. If a pointcloud is passed, then only the connectivity information is propagated to the pointcloud (a subclass of PointCloud may be returned).

  • return_mapping (bool, optional) – Only applicable if a PointCloud or ndarray is passed. Returns the mapping dictionary which maps labels to indices into the resulting PointCloud (which is then used to for building a LabelledPointUndirectedGraph. This parameter is only provided for internal use so that other labellers can piggyback off one another.


:raises : LabellingError: If the given labelled point graph/pointcloud contains less than the expected number of points.
